Fluoropolymers
Fluoropolymers are widely used in automotives, aerospace, semiconductors, electronics and common household appliances because of their unique non-adhesive and low friction properties as well as their superior heat, chemical and weather resistance and superior electrical properties compared with the other polymers.
DESCRIPTION
Fluoropolymers designed to stand the most extreme and unique conditions
Automotive fuel tubes, roofing membranes, semiconductor or wires have in common to endure the most extreme operating conditions. From chemical resistance or harsh outdoor exposure, these parts are expected to stand a broad scope of aggression, while ensuring heat stability or good electrical properties.
Daikin has developed two exhaustive range of fluoropolymers to meet these demanding and various expectations.
- POLYFLON Series, a variety of high-performance PTFE. Available in fine powder, molding powder or dispersion used for tubes, membranes, etc.
- NEOFLON Series, a complete array of melt-processable fluoropolymers such as FEP, PFA, ETFE, PCTFE, suitable for pipe, sealant, roofing, etc.
Fluoropolymers selection guide
This comprehensive selection of fluoropolymers allows engineers to design and develop parts meeting their unique specification. Thanks to a full number of grades available, it enables part producers to dial-in the most appropriated melt flow index, particle size, melting point, strength, flex life, or other polymer property such as
- Heat resistance/heat stability
- Weather resistance
- Low friction
- Superior electrical properties
This vast range of high-performance fluoropolymers was also engineered to meet the most diverse processing methods.
DAIKIN fluoropolymers represent an adequate answer to processing challenges. Because each project specification is unique, DAIKIN Technical Expert supports engineers in selecting the right material and save development time.
